Subject: [PATCH 4.4 05/42] IB/mlx4: Fix port query for 56Gb Ethernet links
Date: Tue, 24 Jan 2017 08:55:15 +0100 [thread overview]
Message-ID: <20170124075509.531413007@linuxfoundation.org> (raw)
In-Reply-To: <20170124075509.299412838@linuxfoundation.org>
4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Saeed Mahameed <saeedm@mellanox.com>
commit 6fa26208206c406fa529cd73f7ae6bf4181e270b upstream.
Report the correct speed in the port attributes when using a 56Gbps
ethernet link. Without this change the field is incorrectly set to 10.
Fixes: a9c766bb75ee ('IB/mlx4: Fix info returned when querying IBoE ports')
Fixes: 2e96691c31ec ('IB: Use central enum for speed instead of hard-coded values')
